KUBECONFIG needs to be updated.

[ajaymare]

as per our documentation its mentioned create kubeconfig secret as KUBECONFIG however as per run-tca.sh its refered as KUBE_CONFIG

Need to change the documentation or update run-tca.sh

KUBE_CONFIG secret needs to base64, however we are expecting it to be clear text.
we need to decode base64 before passing as ARG.
